Hello jaramx, patiofurniture (welcome to our community!) and tstolze (welcome back!),
The gaps you are seeing are related to the work to fix the recent server outage and will slowly backfill with data as we continue operating on our ecosystem.
As you have already noticed, data is locally available on your Shakes, so if you need immediate access to data in those gaps, you can visualize it with one of the methods listed in our manual: How to visualize the waveforms in real time
We apologize for this inconvenience and thank you for your continued patience while we are addressing this situation. You can find all updates on it here: Live Data Issues
